Link G4X AtomX
The AtomX can control up to 2 rotors or 4 cylinders with sequential injection and direct spark. Or, it can be used for up to eight cylinders using batch fire. Now featuring Knock Control. This makes it ideal for naturally aspirated engines that just need a re-tune and don't need all the extra sensors and features that come with our higher level ECUs. The Link G4X AtomX ECU may be our entry-level ECU but don't let its size fool you. The AtomX has expanded data logging and uses the same microcontroller as the entire G4X range! The processing unit is more responsive and has higher bandwidth than its G4+ Atom II predecessor. G4X features 512 megabytes of logging at 32bit using up to 250 channels, each limited to up to 1kHz per channel (by the Operating System), with a maximum of 100 kSamples/sec.
Link G4X StormX
The Link G4X StormX ECU is the latest version of our trusty, mid-sized ECU. With eight injector and eight ignition drives, it allows sequential injection and direct spark on engines with up to eight cylinders or four rotors. The StormX has all the upgrades of the AtomX and MonsoonX but offers more advanced tuning features like a built in Trigger Oscilloscope, Stepper Motor Idle Control, Rotary Oil Metering Pump Control, Onboard Knock Control, Open and Closed Loop Boost Control plus most Motorsport features including Full Gear Shift Control, Antilag and Launch Control.
Link G4X FuryX
The FuryX is a premium ECU like the XtremeX, but with added Onboard Digital Wideband Lambda Control. Now on the G4X platform, the FuryX features a faster processor, faster communications & a huge 512 megabytes of data logging! With 8 injector drives and 6 ignition drives, the FuryX can control up to 3 rotors or 6 cylinders with sequential injection and direct spark, making it an excellent choice for professional level motorsport or more demanding road car applications.
Link G4X XtremeX
The XtremeX has built in E-throttle and all the advanced features including Anti-lag, Cruise Control and Traction Control. With 8 Injector drives and 8 ignition drives the XtremeX can control up to 4 rotors or 8 cylinders with sequential injection and direct spark. The XtremeX is a great choice for professional level motorsport or more demanding road car applications.
THE NEW G5 LINE
The G5 line is purpose-built for direct-injection and combined port/DI engines — where every level of detail counts. When your build goes beyond port injection, the G5 Voodoo Pro and Neo deliver the precision and control to match.
Direct Injection
Native DI support for modern high-pressure fuel systems and combined port/DI strategies.
G5 Architecture
Next-generation processing power for faster, more precise control across every channel.
Port + DI Combined
Run port and direct injection simultaneously with dedicated control for each stage.
Detail-Level Control
Granular tuning where every parameter matters — built for engines that demand precision.
FlagshipLink G5 Voodoo Pro
Link's flagship G5 platform. Full direct-injection and combined port/DI support for the most demanding builds.
NewLink G5 Neo
Next-gen G5 ECU purpose-built for direct-injection and combined port/DI engines. Where every level of detail counts.
